`TO ALL WHOM IT MAY CONCERN:`

Be it known that I, PETER GEISER, of Waynesboro, in the county ofFranklin, and Stateof Pennsylvania,

have invented a new and useful Improvement in Horse-Power Jacks; andI'do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making part of this specification, in which- K Figure lis a perspectiveview of the device. Y

Figure 2 is a central sectional elevation, showing the arrangement ofthe horizontal and'vertical shafts, the gearing, and the means ofconnecting it with the horse or other power by which it is to be driven.

Figure 3 is a view of the clutch, which' is placed in the socket uponthe end of the horizontal shaft; and

Figure 4 is an end view, showing the bevel-wheel, the pins cast upon,the frame to keep the belt or'band from being drawn into the gearing,and the oil-passage, by which the waste oil is carried fromvthe-'vertical to the horizontal shaft. Y

Corresponding letters are used to denote corresponding parts in theseveral figures.

This invention relates to and is an improvement upon jacks forhorse-power, to the driving o r tumblingshafts of which it is to beattached, for the purpose ofV making a belt-connection between suchpower and the machine to be driven, and of multiplying the motion to hegiven to such machine and it consists in the construction of the partsof which it is composed, and their combination and' arrangement, as willbe hereafter described. V y

A is the frame of the device, which is made of any suitable kind ofmetal, and is triangular in form, the rear leg of the triangle having anaperture formed in it, in the form of a segment of a circle, to allow ofthe gear-wheel B revolving therein. 'This frame may be screwed to aframework of wood, of suitable form to receive it, said frame havinggrooves in its ends, to receive hooks for fastening it to the floor orground; or, such frame of wood may be dispensed with, andthe metal framebe fastened to the floor of any building in which it maybe placed.Whenever the jack is to be used in the field, the framework of woodwillbecome necessary, and lwill be used.

B is a bevelled-gear wheel, which is secured tothe horizontal'shaft G.This wheel is madeto mesh into anddrive another bevel-wheel, C, which issmaller than the one B by about two or three to one, and hence, forevery revolution of wheel B, which receives its motion direct from thehorse-power or other motor, the pinion C, and consequently thebevel-,wheel D, will have from two to three, or more, revolutions to oneof wheel B. C is a bevelled wheel, which is placed upon a verticalshaft, F, and whichrests upon the apex of the frame A, and is arrangedto meshinto the wheel B, as above described.A This wheel has, upon itsupper face, a boss or projection, upon which the bevel-wheel, afterbeing bored, is fitted, and firmly secured. There is also a boss formedupon the under side of this wheel, which is turned oif, and is madetapering, it being smallest at its lower end, so as to iit intoa recesswhich is formed in the apex of the frame A, or, it may be, in a separatepiece of metal, secured to the frame for the purpose, the object of saidrecess being twofold: first, it serves to y steady and keep in line thelower end of. the gear-Wheel C, or the sleeve upon which it may befastened; and,

second, it serves as a reservoir for the oil which has been used forlubricating said wheel upon iits'shaft, as will be more fully describedhereafter.

D is the bevel-wheel, which is keyed to a projection formed upon thepinion C, as above described.v

E is thevjournal-box for the horizontal shaft G, which box or bearing isformed of a solid piece of metal,

bored to receive said shaft, and which is of the proper contour to tinto that part ofthe frame A where the legs diverge from the body ofsaid frame, which arrangement brings the centre of said box directlyunder the centre of the vertical vshaft-F, upon which the pinion Crotates. This journal-box is provided, upon its upper side,

with a boss or projection, b, through which a smallhole, f, is bored, topermit of the passage of oil for lubrieating the shafts.- In' the sideof the frame A a semicircular recess, a, is formed, into which theprojection upon the journal-box fits. Upon the apex ofY the frame A, orwithin a separate piece of metal placed there for the purpose, a recessis formed, as before stated, into which-the lower portion of the pinionenters, and which also serves as a reservoir for the oil that passesdownward around the shaft F. The semicircular groove above referred toextends up to the top of this oil-reservoir, and a communication'isformed between the two, either by boring a hole through the side of saidrecess, or by cutting away a portion of the same, so that the oil, afterrising to a certain height in the reservoir, shall iow over, and rundown the recess in the side ofthe frame, and into the journal-box,through the aperturef, so as to be again used for lubricating the shaftG, after which it passes'oii' through the spout L, formed upon the underside of said box, and it may, if desired, be allowed to run down uponthe gear-wheel B to'its periphery, where it will be carried up, and thuslubricate the teeth of both of the gear-wheels.

F is the vertical shaft, upon which the pinion C rotates. Said shaftpasses down through the upper portion of theframe, and enters thejournal-box E, to which it is secured by being screwed thereon, while,at the same time, it secures said bor in its position, thus serving thedouble purpose of a. shaft for the wheel C, and a boltl for holding'inits place the journal-box E.

G is the horizontal shaft, which carries the gear-wheel B, and upon theouter end of which the couplingbox H is secured.

H is a coupling-box, firmly secured to the shaft G, and has placedwithin it a clutch, k, and spring, al, so arranged that, whenan excessof power is applied to the jack, the spring d, which holds the clutch incontact with corresponding projections upon -the end of the flange orhead, I, will yield, and permit the shaft which drives the jack torevolve, without revolving the shaft G of said-jack.

It will be apparent, vfrom the above description, that thiscoupling-device may be so arranged, by the aid of the spring d, thatonly a given amount of power can be transmitted through the jack, andthat, by thus arranging it, much of the danger of breaking threshing andother machines, which now exists, may be avoided.

I is the outer section or flange of the coupling-head, having formedupon its inner face projections corresponding with those upon the'collar K. This portion of the coupling is screwed to the shaft G, byhaving a `hole bored through its'centre, to receive the end of saidshaft, upon the end of which, and outside of said ange,

a. nut is placed, which holds said portion in contact with the spring,as above described.

K is the loose collar above referred to, ywhich is placed within theportion H of the coupling-box, the construction of which is clearlyshown in iig. 3 of the drawings.

a is the semicircular oil-groove, formed in the side of the frame A, asabove described.

b b are pinsor projections, secured to or cast upon the fra-me A, forthe purpose of preventing the bolt from being drawn into the gearing,and injured thereby, should it slip oif from the pulley DA while themachine is -inmotion.

c is what may be termed a gimbal-joint, which is secured to ears formedupon the outer side of the outer portion I of the coupling-box H, and isfor the purpose of attaching the driving-shaft to the jack, and, at thesame time, provides for their being slightly out oY'f line with eachother.

d is the spring, arranged as above described.

,e is the aperture through which oil is poured to lubricate the verticalshaft F.

fis the hole bored through the journal-box.

gis an oil-hole; for lubricating the shaft G independently of theabove-named arrangement, should it become necessary. Y

.7L is the oil-spout, attached to the under side of the journal-boxE,`to carry away'the oil, as above described.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination and arrangement of the frame A and journal-box E',substantially as and for the pur-l pose described.` g

2. The combination and arrangement of the vertical shaft F and thejournal-box E, substantially as and for the purpose described.

3. In combination with the above, the combination oi' theratchet-coupling and the shaft G, substantially as-and for the purposedescribed.

4. The construction of the frame A, and they arrangement, with referencethereto, of the journal-box E, shaft F, gear-wheels B and C, and pins orguards b b.

5. The arrangement of the oil-passages e, a,f, and'h, substantially asand for the purpose set forth. In testimony whereof, I have signed myname to this specification in the presence of two subscribing witnesses.

PETER GEISER.
